Title: Process for drying hydrophobic amino acids with improved process for increased bulk density
Inventor: DUEPPEN DANIEL
IPC: A23K1/00
Filed: 1996-01-18
Granted: 1999-11-23
Abstract: A process for improving the solubility of hydrophobic amino acids in which hot saturated aqueous solutions of at least two different amino acids are first combined. A first step includes making a hot saturated aqueous solution of a first and hydrophobic amino acid having a low solubility in water. A second step includes making a hot saturated aqueous solution of a second and hydrophilic amino acid having a high solubility in water. Then the two hot saturated aqueous solutions are mixed to prepare a combined hot solution mixture, arid dried. The resulting product is an amino acid food supplement which is blended into animal feed. The preferred amino acids are tryptophan and lysine, when the animal is a domestic farm animal. A preferred ratio is where the concentration of tryptophan is greater than 50 grams per liter and the concentration of lysine is greater than 300 grams per liter.

Granted: 1999-09-21
Abstract: A system and method which determines a number of electronic price label (EPL) data message transmission attempts to an EPL. A transmitter transmits a data message to the EPL. A receiver receives a return signal from the EPL. A storage system stores a status flag representing a first number of times the data message is transmitted by the transmitter to the EPL, the status flag being based upon an established signal to noise (S/N) ratio.  A communication base station (CBS) determines a new S/N ratio from the return signal.  A runtime analyzer program determines whether the new S/N ratio is below a range of S/N ratios that includes the established S/N ratio, and if it is, provides a new status flag representing a second number of transmission times greater than the first number of transmission times.  The transmitter transmits a subsequent data message the second number of times.

Abstract: An apparatus for use with a water treatment unit and, in particular those having a treatment cartridge, that indicates the end of life of the unit. The apparatus comprises a housing with at least one opening for the passage of liquid to a chamber, formed by the interior of the housing and the water treatment unit. The chamber includes a support member mounted to the housing. A float is rotationally mounted on the support member. The support member limits float movement to a predetermined distance upon each rotation of the float, resulting from each cycle (use) of the water treatment unit. Once the float has made a specific number of rotations and has travelled the complete distance of the support member (as water fills and drains from the chamber), the float rests in a position where it is visible through an opening in the housing, indicative of the end of life of the water treatment unit.

Abstract: A chemical sensor (1) for selectively detecting an analyte in a solution is described. The sensor comprises a flow-through chamber (2), a selective membrane (3), transducer means (4), an inlet (5) for a liquid flow containing a recognition element, and an outlet (6). There is also described a method of selectively detecting an anlyte in a solution, wherein a recognition element is contacted with the solution containing the analyte via a selective membrane, said contact resulting in a response detectable by transducer means. The recognition element is injected into a flow, the flow is passed into a flow-through chamber comprising the transducer means and the selective membrane, where it is contacted with the analyte passing from the solution outside the selective membrane, whereby the recognition element and the analyte interact to provide a signal which is detected by the transducer means. The use of the chemical sensor for detecting of analyte(s) in a reactor system, a flow system or in an in vivo system is also described.

Title: Recording device using continuous paper and method of feeding continuous paper
Inventor: MIYAKE HIROMASA
IPC: B65H35/00
Filed: 1997-12-23
Granted: 2001-10-30
Abstract: A recording device operable with continuous paper in the form of a roll of the present invention includes a pair of drive rollers for selectively rotating the roll in the forward direction for paying out the paper or in the reverse direction.  A controller causes the drive rollers to rotate in the reverse direction in response to a preselected signal.          Bar codes representative of serial numbers are printed on one side edge of the paper.  While the roll is rotated in the reverse direction, a number identification circuit reads the bar codes 41 and detects the leading edge of the paper on the basis of one bar code positioned at the leading edge and another bar code adjoining a roll position which the leading edge  overlies.   When  the  number  identification  circuit detects  the  leading  edge,  the  controller  switches  the direction of rotation of the roll from reverse to forward.          Subsequently, a separator is brought into contact with the periphery of the roll in order to separate the paper from the roll and pays out the paper in accordance with the forward rotation.

Abstract: The invention concerns a self-propelled impact compaction machine that includes a chassis (20) with a prime mover thereon. The chassis (20) carries ground engaging wheels (21) at least some of which are driven by the prime mover. Compaction of soil is achieved by one or more impact compactor masses (24) which have out-of round shapes so as to apply periodic impact blows to the soil surface when rolled over that surface.    The mass or masses (24) are connected resiliently to the chassis (20) and define a compaction track width measured from one lateral extremity of the mass or masses (24) to the opposite lateral extremity of the mass or masses. The ground engaging (21) wheels of the chassis define a maximum wheel track width which is not substantially different in magnitude to the compaction track width, with the desirable result that the chassis (20) enjoys substantial roll axis stability.

Abstract: A radial-flow, wide-pouring molten-metal distributor comprising a curved or arcuate overflow weir which is normally horizontal on its top and which is concave on its upstream side as viewed from above. Over this arc-shaped overflow weir flows molten metal to be continuously cast in an open pool. An impetus is thereby imparted to the molten metal along diverging radial lines. The flow so impelled continues radially onto a horizontal apron. The flow spreads fanwise to the desired width which may be as much as six times the width of the weir. Thence, the metal cascades or flows uniformly into the casting apparatus. The overflow weir is preferably supplemented by a skimmer mounted above it in substantially uniform spaced aligned relationship, thereby completing a slot beneath the skimmer through which the molten metal flows. When employed for the casting of wide, thin product, the invention results in a far more uniform and gentle distribution of metal than heretofore available. Dribbling and "beards" are eliminated. Swirls and porosity are reduced. The temperature profile across the section being cast is rendered more uniform, thereby permitting a lower temperature of the supply of molten metal entering this novel distributor.
